Аннотация
The character of alkaline (M<sup>+</sup>= Li, Na, K) and alkaline earth metal ions (M<sup>2+</sup>= Be, Mg, Ca) interactions with disilyne and acetylene has been studied by using high-level <i>ab initio</i> computations. The interaction energies were calculated at MP2/6-311++G(2<i>d</i>,2<i>p</i>) level. These calculations show that the size and charge of cation are two significant factors that affect the character of interaction. AIM and NBO analyses of M<sup><i>n</i>+</sup>…X<sub>2</sub>Y<sub>2</sub> interactions specify that the variation of densities and the extent of charge transfers upon complexation correlate well with the obtained interaction energies.
